Great webshop, very good communication, fast shipping, good packaging. But never understood why the Fusion range are only available to some cars - and not mine (2009 Peugeot 407 sw 2.7 hdi).
Everything is working fine.
Instructions for DIY installation should be more detailled and specific for every single car model. Simple things as intake air filter position makes wiring more difficult in my fabia than in volks.
You should send a tracking number. I ordered as express and it took 10 days to arrive and i couldnt track it.
Good communication and double check regarding the motor type of my BMW by TuningBox. Fast delivery of the box. Everything is working fine without any warninglight. Power increase is very noticeable.
